ABSTRACT

Six Sigma is a process improvement philosophy that views all works as processes that can be defined, measured, analyzed, improved, and controlled through the use of problem-solving and statistical tools. The goal of Six Sigma is to prevent defects by eliminating variation and waste, while delivering value-added and quality products to the customer. Six Sigma methods originated at the Motorola Company and were further refined by Jack Welch on leaving the Motorola Company and becoming the chief executive officer of General Electric. Design for Six Sigma (DFSS) takes these basic principles and applies them to product, process, and service development. DFSS has a five-phase structured approach: define, measure, analyze, design, and verify. This method is used to prevent design problems instead of using additional resources to fix the problems in the future.
